[FONT="][/FONT][FONT="]Yet most experiments looking at multicellular organisms have so far failed to produce any information on such mutations.[/FONT]
Except the examples of the beneficial humans mutations in humans that I linked to o course. Oh and all that antibiotic resistance that you have to deal with in your job.
And here's some for other species.
Examples of Beneficial Mutations and Natural Selection

Sorry to say this but you are. You are also ignoring your own evidence of deleterious mutations being removed from the gene pool due to miscarriage and their effects on reproductive success. While the majority of phenotypic mutations are deleterious the majority of phenotypic mutations are also removed from the gene pool because those affected do not reproduce.
You obviously missed reading Nachman, M. W. and S. L. Crowell. 2000. Estimate of the mutation rate per nucleotide in humans. Genetics 156(1): 297-304 and Perfeito, Lilia, Lisete Fernandes, Catarina Mota and Isabel Gordo. 2007. Adaptive mutations in bacteria: High rate and small effects. Science 317: 813-815.
